201116396 六、發明說明： 【發明所屬之技術領域】 本發明係關於藉由夾入金屬基調裝飾薄片之複數個樹 脂進行複合成形而構成之金屬基調裝飾樹脂成形品、以及 金屬基調裝飾樹脂成形品之製造方法。 【先前技術】 在複數個樹脂層間埋設具備裝飾層之嵌入薄片（以下 簡稱爲「裝飾薄片」）之多層成形品，例如是經由以下步 驟而製造出。將第1模具（模穴模具）和配置有裝飾薄片 的第2模具（第1芯模）合模，對形成於第1模具和裝飾薄 片間的第1模穴射出第1樹脂而在裝飾薄片的一側形成第1 樹脂層。接著，在第1模具（模穴模具）上保持第1樹脂層 和裝飾薄片的狀態下，將另外的第3模具（第2芯模）和第 1模具（模穴模具）合模，對形成於裝飾薄片和第3模具（ 第2芯模）間的第2模穴射出第2樹脂而在裝飾薄片的另一 側形成第2樹脂層。藉此製得在複數個樹脂層間埋設裝飾 薄片之樹脂成形品（參照專利文獻1 )。 依據上述構造，由於能在裝飾薄片的兩面積層第1樹 脂層和第2樹脂層，在所製造的多層成形品之第1樹脂層和 第2樹脂層當中若在表面側的樹脂層使用透明性樹脂’則 可透視形成在裝飾薄片上的模樣。 〔專利文獻1〕日本特開2005-668 34號公報 201116396 【發明內容】 如第3 1圖所示’配置在多層成形品之第1樹脂層8和第 2樹脂層9間的裝飾薄片5，例如是由蒸鍍層6和基體薄片7 所積層而成。在此情況，蒸鍍層6是對多層成形品賦予裝 飾的層。然而，由於蒸鍍層6本身非常薄，要僅藉由蒸鍍 層6來對多層成形品賦予立體感的裝飾是困難的。 此外，當多層成形品的形狀複雜的情況，裝飾薄片5 的形狀也必須形成與多層成形品一致的形狀。在此，由於 蒸鍍層6非常薄’會有無法配合多層成形品的形狀改變而 在蒸鍍層6產生龜裂（裂痕）的情況。再者，當施加於蒸 鍍層6之圖案和文字等是局部形成於基體薄片7上的情況， 若多層成形品的形狀變複雜，蒸鍍層6會被拉伸，而使多 層成形品之蒸鍍層6的圖案等的對準作業變困難。 本發明是爲了提供：配置金屬基調的薄片層作爲中間 層以提昇裝飾性之金屬基調裝飾樹脂成形品，以及金屬基 調裝飾樹脂成形品之製造方法。 本發明的金屬基調裝飾樹脂成形品之第1特徵構造， 係具備薄片層、第1樹脂層以及透明的第2樹脂層；該薄片 層具有基體薄片及埋設於該基體薄片的一面之金屬基調構 件；該第1樹脂層是在前述基體薄片之另一面上進行成形 ，該第2樹脂層是重疊在前述薄片層的前述基體薄片及前 述金屬基調構件上而進行成形。 如此般，由於金屬基調構件配置成埋設於基體薄片的 狀態，例如能使金屬基調構件的厚度增厚至基體薄片的厚 201116396 度左右。結果，可對樹脂成形品賦予立體金屬基調構件的 裝飾。此外，由於在第1樹脂層和第2樹脂層間配置金屬基 調構件且第2樹脂層是透明的，因此可從樹脂成形品的表 面側看到金屬基調構件之表面模樣或立體形狀。 本發明的金屬基調裝飾樹脂成形品之第2特徵構造， 前述金屬基調構件的周緣表面部之至少一部分是朝表面側 呈凸狀，且形成越靠近周緣側厚度越小。 依據此構造，在金屬基調構件之周緣表面部的表面側 呈凸狀且越靠近周緣側厚度越小的部分可反射來自外部 的光。結果，在從外部觀看樹脂成形品時可進一步增加金 屬基調構件的立體感。 本發明的金屬基調裝飾樹脂成形品之第3特徵構造， 前述薄片層係具有：與前述基體薄片合作而挾持前述金屬 基調構件之被覆層。 依據此構造，金屬基調構件是藉由基體薄片和被覆層 確實地保持，在樹脂成形的過程中不容易發生金屬基調構 件的位置偏移。因此，可穩定地對樹脂成形品賦予立體的 金屬基調構件所形成的裝飾。 本發明的金屬基調裝飾樹脂成形品之製造方法的第1 特徵手段係具備：在基體薄片的一面貼附金屬基調構件的 步驟；以讓前述金屬基調構件接觸第2模具的方式將前述 基體薄片配置於前述第2模具的步驟；對於前述第2模具將 第1模具合模’而在配置於前述第2模具之基體薄片和前述 第1模具之間形成第1樹脂注入用的第1模穴之步驟；對前 201116396 述第1模穴注入第1樹脂’藉由所注入的前述第1樹脂的壓 力將前述基體薄片緊壓於第2模具而成爲將前述金屬基調 構件埋設於前述基體薄片的狀態’且在前述基體薄片之未 貼附金屬基調構件側進行第1樹脂層的成形之步驟；在前 述第1模具上保持前述第1樹脂層及前述基體薄片的狀態下 ，讓前述第1模具離開前述第2模具，並將前述第1模具與 其他的第3模具進行合模，而在前述基體薄片和前述第3模 具之間形成第2模穴的步驟：以及對前述第2模穴注入透明 的第2樹脂而進行第2樹脂層的成形之步驟。 依據此特徵手段，在注入第2樹脂而進行第2樹脂層的 成形時由於金屬基調構件成爲被埋設於基體薄片的狀態’ 即使第2樹脂通過金屬基調構件上，金屬基調構件仍不會 被第2樹脂剝離。此外，由於金屬基調構件配置成埋設於 基體薄片的狀態，例如能使金屬基調構件的厚度增厚成基 體薄片的厚度左右，結果，可進行賦予立體的金屬基調構 件裝飾之樹脂成形品的製造。此外，由於在第1樹脂層和 第2樹脂層之間配置金屬基調構件且第2樹脂層是透明的， 可製造出從表面側能看到金屬基調構件表面的模樣或立體 形狀之樹脂成形品。 再者，由於是在基體薄片成形後才配置金屬基調構件 ，藉由基體薄片的成形所導致之像蒸鍍層那樣的金屬基調 構件之拉伸並不會發生，在金屬基調構件及基體薄片上不 會產生龜裂。結果容易將金屬基調構件配置在樹脂成形品 之期望的位置。 -8 - 201116396 2 第 的 法 方 造 製 之 品第 形述 成前 脂或 樹片 飾薄 裝體 調基 基述 Up 以BI 金在 的是 明’ 發段 本手 徵 特 部 周 外 的 層 脂 樹 第 與 且 出 突 部 外 的 品： 形第 成述 旨 Ί,υ τττ^ ΊΠΠ 樹行 飾進 裝在 調 ·’ 基片 屬出 金突 朝之 : 接 成抵 形具 模 驟 步 之 形 成 的 層 旨 樹 模 2 第 述 前 入 注 路 流 的 片 出 突 述 前 向 面 由 經 是 脂 樹 2 第 述。 前穴 依據此特徵手段，所注入的第2樹脂，會通過被突出 片和第3模具包圍的空間才接觸基體薄片，這時，即使高 溫的第2樹脂接觸基體薄片而使第2樹脂的熱傳送至基體薄 片，由於基體薄片的熱通過突出片而容易傳送至第1模具 ，因此基體薄片很難變高溫。此外，特別是突出片設置於 基體薄片的情況，從第2樹脂傳送至基體薄片的突出片之 熱，由於是先沿著突出片的寬度方向擴散後才傳送至突出 片以外的基體薄片主體，因此相較於未設置突出片而從第 2樹脂的熱是直接傳送至基體薄片主體的情況，基體薄片 的局部不容易變高溫。因此，可防止基體薄片之熔融和金 屬基調構件的變形（澆口附近移位，gate-area shifting ) 。特別是基體薄片之突出片附近的部分容易變高溫，而使 基體薄片容易發生熔融但該突出片附近部位的熱可藉由 突出片傳送至第1模具，藉此可適切地防止基體薄片之熔 融。結果，可抑制基體薄片中所埋設之金屬基調構件的位 置發生偏移的現象。 此外，依據此特徵手段’只是在第1樹脂層和第2樹脂 層之間設置埋設有金屬基調構件之基體薄片，第2樹脂的 201116396 熱會通過突出片而傳送至第1模具。如此，可減少傳送至 第1樹脂層的熱量，可充分地阻止第1樹脂層發生再熔融的 現象，而能充分地減少樹脂成形品的厚度。 本發明的金屬基調裝飾樹脂成形品之製造方法的第3 特徵手段’在進行前述第2樹脂層的成形之步驟，是在將 前述突出片的緣部固定的狀態下進行前述第2樹脂的注入 〇 依據此特徵手段，在注入第2樹脂時，可避免基體薄 片的位置偏移，而能防止基體薄片之浮動和捲曲。藉此， 可良好地維持突出片和第1模具的接觸，基體薄片的熱可 通過突出片而確實地傳送至第1模具。因此，可確實地防 止基體薄片發生熔融。結果，可抑制基體薄片中所埋設之 金屬基調構件的位置發生偏移的現象。 本發明的金屬基調裝飾樹脂成形品之製造方法的第4 特徵手段，在進行前述第2樹脂層的成形之步驟，是在面 向前述突出片之前述流路沿著前述第2模穴而連接的狀態 下，沿著前述突出片的延伸方向注入樹脂。 依據此特徵手段，所注入的第2樹脂，不致與基體薄 片的突出片及主體部位進行正面碰撞的接觸，而是沿著基 體薄片之該等部位順利流過而進入第2模穴。因此，相較 於所注入的樹脂是與基體薄片進行正面碰撞接觸而進入模 穴的構造，樹脂在基體薄片附近發生沉澱的可能性減低， 樹脂熱的影響不容易及於基體薄片。結果，可抑制基體薄 片中所埋設之金屬基調構件的位置發生偏移的現象。 -10- 201116396 本發明的金屬基調裝飾樹脂成形品之製造方法的第5 特徵手段，在進行前述第2樹脂層的成形之步驟，是在藉 由第1模具支承的前述基體薄片和配置於第3模具的內面之 裝飾薄膜之間形成前述第2模穴，在將緊固具（用來將前 述裝飾薄膜固定於前述第3模具）設置在與前述突出片的 基端部接觸的位置之狀態下，注入樹脂。 依據此特徵手段，裝飾薄膜，在最終成形品之主體部 分上要組裝裝飾薄膜的部位之前方位置爲止，是藉由緊固 具按壓在第3模具上，因此可抑制裝飾薄膜從第3模具的凹 部內面上浮的現象，而能獲得品質良好的成形品。 本發明的金屬基調裝飾樹脂成形品之製造方法的第6 特徵手段，在進行前述第2樹脂層的成形之步驟，在形成 於前述基體薄片之前述突出片的前端退避至設置於前述第 1模具之段差狀凹部的狀態下，注入樹脂。 依據此特徵手段，基體薄片之突出片的前端被該段差 狀的凹部保護，藉此可防止樹脂流造成基體薄片的浮動和 「捲曲」等，而能獲得品質良好的成形品。 本發明的金屬基調裝飾樹脂成形品之製造方法的第7 特徵手段，前述金屬基調構件是使用：周緣表面部的至少 一部分朝表面側呈凸狀，且形成越靠近周緣側厚度越小的 構件’在注入前述第2樹脂時，前述第2樹脂是以從前述厚 度小的周緣部側朝向前述金屬基調構件流動的方式進行注 入。 依據此特徵手段，第2樹脂是以從金屬基調構件之厚 -11 - 201116396 度小的周緣部側朝向金屬基調構件流動的方式進行注入， 因此可減少金屬基調構件的表面部和第2樹脂接觸所產生 的摩擦力，而能抑制基體薄片中所埋設之金屬基調構件的 位置發生偏移的現象。 此外，所製造之樹脂成形品，在金屬基調構件之周緣 表面部的表面側呈凸狀且越靠近周緣側厚度越小的部分 可反射來自外部的光。結果，在從外部觀看樹脂成形品時 可進一步增加金屬基調構件的立體感。 本發明的金屬基調裝飾樹脂成形品之製造方法的第8 特徵手段，是在前述基體薄片的一面貼附前述金屬基調構 件後，以覆蓋前述金屬基調構件的方式將其他樹脂被覆於 前述基體薄片。 在第2模穴注入第2樹脂時，若金屬基調構件的表面部 從基體薄片露出，所注入的第2樹脂會流過金屬基調構件 的表面部。在此情況，第2樹脂和金屬基調構件的表面部 間會產生摩擦力，而可能使金屬基調構件的位置改變。然 而，依據本特徵手段，金屬基調構件的表面部是藉由被覆 層所保護。亦即，在第2樹脂注入第2模穴時，第2樹脂雖 會和被覆層接觸，但不致接觸金屬基調構件。結果，金屬 基調構件不致直接受到所注入的第2樹脂的作用，可抑制 樹脂成形品中之金屬基調構件的位置偏移，而能製造出裝 飾性優異的樹脂成形品》 【實施方式】 -12- 201116396 〔第1實施形態〕 以下說明本發明的金屬基調裝飾樹脂成形品F2及其製 造方法。 〔在基體薄片貼附金屬基調構件的步驟〕 基體薄片2是事前成形爲既定形狀的樹脂成形體，在 該基體薄片2上貼附金屬基調構件1。金屬基調構件1，是 包含可轉印的電鑄貼片材、金屬珠粒等。具體而言，在金 屬基調構件1爲電鑄貼片材的情況，將電鑄貼片背面的剝 離紙剝除，在基體薄片2之待轉印的部位連同薄膜一起貼 附。藉由從薄膜上方輕輕地摩擦電鑄部分而使其固定在基 體薄片2後，將薄膜剝除。如此般如第1圖所示，在基體薄 片2貼附金屬基調構件1。 在基體薄片2上貼附金屬基調構件1的步驟，由於是在 基體薄片2成形爲既定形狀之後才進行，因此不致隨著基 體薄片2的形狀改變而在金屬基調構件1產生龜裂。此外， 藉由在基體薄片2的成形後才貼附金屬基調構件1，自然可 決定樹脂成形品上之金屬基調構件1的位置，而使金屬基 調構件1在樹脂成形品上的對準變容易。 此外，在基體薄片2上雖可形成各種的圖案，但採用 未形成模樣的素地彩色薄片等亦可。基體薄片2可由丙烯 酸系樹脂、聚烯烴系樹脂等各種的樹脂所構成，若採用聚 碳酸酯系樹脂或P E T等的高耐熱性的樹脂來構成的話，對 於在二次成形用的樹脂注入時基體薄片2受該樹脂熱的影 -13- 201116396 響而再熔融的現象，亦即所謂「澆口附近移位」現象有良 好的效果。「澆口附近移位」是指，當高溫（2 5 (TC〜2 8 0 °C )的二次成形用樹脂接觸嵌入薄片時，該樹脂的熱會傳 送至嵌入薄片，另一方面該熱受到一次成形品之隔熱效果 而不容易傳送至模具，因此嵌入薄片無法被模具冷卻而變 得高溫發生熔融，結果施加於裝飾層的圖案等會流動而發 生變形的現象。基體薄片2的厚度宜爲7 5~2 0 0μπι的範圍， 而以125〜150μιη的範圍最容易使用。 接著說明製造金屬基調裝飾樹脂成形品F2時所使用的 雙色成形用模具。 雙色成形用模具，是設置於雙色成形機（僅圖示其一 部分），如第2圖~第5圖所示係具備：可動模具11Α、11Β (都是第1模具的一例）、第1固定模具12(第2模具的一 例）以及第2固定模具13 (第3模具的一例）。 雙色成形機係具備：固定平台14、相對於固定平台14 可旋轉且能進退之旋轉平台15。固定平台14係具有第1固 定模具12及第2固定模具13，旋轉平台15具有可動模具11Α 、11Β。可動模具11Α、11Β分別與第1固定模具I2及第2固 定模具1 3相對置。依據此構造，如第3圖所示，若將旋轉 平台15按壓於固定平台14，可動模具11Α、11Β與第1固定 模具1 2及第2固定模具1 3可同時地合模，而能同時進行第1 樹脂的注入及第2樹脂的注入。 如第2圖所示，在合模前的狀態，在與第2固定模具1 3 對置的可動模具ΠΒ上，保持著上一步驟所成形的一次成 14 - 201116396 形品F1 (第1樹脂層25和薄片層3)。另一方面，在第1固 定模具12上，保持著後續的一次成形所使用之基體薄片2 。雙色成形機，係具備用來將基體薄片2設置在第1固定模 具12上之機械人裝置16。 在第2固定模具13設有：用來送出裝飾薄膜（轉印箱 )30之薄膜送出裝置31、用來捲取裝飾薄膜30之捲取裝置 32、將裝飾薄膜30按壓於可動模具1 1 A、1 1B側之矩形框狀 的緊固具33。 裝飾薄膜30，是將熔接於第2樹脂層26之裝飾部30a和 操作用的基體薄片30b—體化而構成，在裝飾部30a轉印到 第2樹脂層26後的任意步驟，將基體薄片30b剝除。裝飾部 3〇a—般而言具有：最終成爲多層成形品的最外層之剝離 保護層、熔接於樹脂層之黏著層，一般是在剝離保護層和 黏著層之間設置圖案層。 作爲基體薄片的材質，例如可使用：聚丙烯系樹脂、 聚苯乙烯系樹脂、聚醯胺系樹脂、聚酯系樹脂 '丙烯酸系 樹脂、聚氯乙烯系樹脂等的樹脂薄片；鋁箔、銅箔等的金 屬箔；玻璃紙、塗層紙、賽璐凡等的纖維素系薄片等；或 是其等所複合成的薄片等。此外，爲了提昇基體薄片30b 的剝離性’在基體薄片30b和裝飾部30a之間形成胺基醇酸 系樹脂所構成的脫模層亦可。作爲基體薄片3 0b的厚度， 宜爲5〜500μηι。 作爲剝離保護層的材質’例如除了丙烯酸系樹脂、聚 醋系樹脂、聚氯乙烯系樹脂、纖維素系樹脂 '橡膠系樹脂 -15- 201116396 、聚氨酯系樹脂、聚醋酸乙烯系樹脂等以外，還能使用氯 乙烯-醋酸乙烯共聚物系樹脂、乙烯-醋酸乙烯共聚物系樹 脂等的共聚物。當剝離保護層要求硬度的情況，亦可選定 紫外線硬化性樹脂等的光硬化性樹脂、電子線硬化性樹脂 等的放射線硬化性樹脂、熱硬化性樹脂等。 黏著層，應選擇與待熔接的對象樹脂具有高親和性的 材質。例如當被轉印物的材質爲丙烯酸系樹脂的情況，可 使用丙烯酸系樹脂。又當被轉印的材質爲聚苯醚.聚苯乙 烯系樹脂、聚碳酸酯系樹脂'苯乙烯共聚物系樹脂、聚苯 乙烯系混合樹脂的情況，可使用與該等樹脂具有親和性之 丙烯酸系樹脂、聚苯乙烯系樹脂、聚醯胺系樹脂等。此外 ’當樹脂成形品的材質爲聚丙烯樹脂的情況，可使用氯化 聚烯烴樹脂、氯化乙烯-醋酸乙烯共聚物樹脂、環化橡膠 、香豆酮-茚樹脂。黏著層的厚度宜爲0.5~50μιη。 雙色成形模具，只要具備能將金屬基調構件1埋設於 基體薄片2的構造即可，假使是不具備裝飾薄膜30、薄膜 送出裝置31、薄膜捲取裝置32及緊固具33的構造也不會發 生問題。 又關於第1樹脂和第2樹脂，可爲不同顏色的樹脂，亦 可爲彼此的硬度等其他特性不同的樹脂。例如，第1樹脂 是使用聚碳酸酯樹脂、ABS樹脂或聚碳酸酯樹脂和ABS樹 脂的合金樹脂等：第2樹脂是使用ΡΜΜΑ (聚甲基丙烯酸甲 酯樹脂）。特別是第1樹脂使用ABS樹脂，第2樹脂使用 PA AM的情況，由於ABS樹脂的成形性高。可良好地進行 -16- 201116396 雙色成形等的多層成形。而且，即使ABS樹脂的軟化溫度 比PMMA的軟化溫度低，藉由基體薄片2的存在，在注入 PMMA時，可抑制成形好的ABS樹脂受到PMMA樹脂的熱而 發生變形。 在可動模具11A、11B設有：用來固定基體薄片2的一 部分之滑動塊1 7 (固定手段的一例）、以及在合模時收容 緊固具33之大致矩形的凹槽18。該等的詳細構造顯示於第 6圖及第9圖。如第10圖（顯示固化後從可動模具11A、11B 取下的二次成形品F2)所示，在基體薄片2的一邊形成梯 形的突出片2a之緣部2b，該緣部2b是被前述滑動塊17所固 定。又在可動模具11B形成：在第2固定模具13和可動模具 1 1B合模時可收容突出片2a之輔助模穴22A。此外，用來注 入第2樹脂之第2澆口 24，是設置在第2樹脂一定要通過輔 助模穴22A才能注入第2模穴22的位置。 詳而言之，若可動模具11B和第2固定模具13合模，在 兩者間會形成讓第2澆口 2 4和第2模穴2 2互相連通之連通流 路40。從第2澆口 24射出之第2樹脂，經由該連通流路4〇而 注入第2模穴22。連通流路40係包含：從第2澆口 24出發而 到達附近的緊固具3 3之直線狀的第1連通部4 1、迂迴於緊 固具33周圍之大致C字狀的第2連通部42、從第2連通部42 出發而朝向遠方的緊固具33之輔助模穴22A。如第6圖所示 ,可收容突出片2a之輔助模穴22A，是形成越靠近一次成 形品F 1越寬之漸寬狀。 如此般構成連通流路40的結果，在注入第2樹脂時， -17- 201116396 始終能讓第2樹脂通過突出片2 a和第2固定模具13所包圍的 空間才開始接觸基體薄片2。因此，即使高溫的第2樹脂接 觸基體薄片2而將第2樹脂的熱傳送至基體薄片2’基體薄 片2所承受的熱可透過大面積的突出片2a而有效地往可動 模具11B(11A)散熱，因此基體薄片2不致變得過度高溫 ，而防止基體薄片2發生熔融。而且，在合模時，緊固具 33是將滑動塊17往突出片2a側上推而使其滑動移動，以藉 由滑動塊17和可動模具11B來挾持固定突出片2a的緣部2b ，因此在注入第2樹脂時可防止發生基體薄片2位置偏移的 現象。藉此，由於能良好地維持突出片2a和可動模具11B 的接觸，基體薄片2的熱可通過突出片2a而確實地傳送至 可動模具11B，又突出片2a之緣部2b的熱可確實且高效率 地散熱至可動模具1 1 B及滑動塊1 7。如此，可確實地防止 基體薄片2之熔融，而能抑制埋設於基體薄片2之金屬基調 構件1的位置發生偏移的現象。而且，可防止基體薄片2之 浮動及「捲曲」等，而能良好地製造多層成形品。 以下說明，使用該雙色成形機，將貼附有金屬基調構 件1之基體薄片2夾在複數個樹脂層間之金屬基調裝飾多層 成形品之製造方法。 〔配置基體薄片的步驟〕 如第2圖所示，在將可動模具i〗a和第丨固定模具1 2開 模的狀態下，使用機械人裝置1 6將貼附有金屬基調構件1 之基體薄片2設置在第1固定模具12。在此，貼附於基體薄 -18- 201116396 片2之金屬基調構件1，是以接觸第1固定模具12的方式配 置於基體薄片2，基體薄片2是被設置於第1固定模具I2之 吸引裝置（未圖示）所保持。 〔形成第1模穴的步驟〕 如第3圖所示，使旋轉平台1 5朝固定平台1 4側移動而 相對於第1固定模具12使可動模具1 1A進行合模，在藉由第 1固定模具12支承之基體薄片2和可動模具丨丨A之間形成第1 模穴2 1。 〔第1樹脂層的成形步驟〕 如第7圖所示’從第1澆口 2 3將第1樹脂朝向第1模穴2 1 射出。若第1樹脂注入第1模穴2 1，藉由所注入的第1樹脂 的壓力會將基體薄片2按壓於第1固定模具12。這時，在金 屬基調構件1的附近，基體薄片2會配合金屬基調構件1的 形狀而被拉伸，而使金屬基調構件1埋入基體薄片2，藉此 形成金屬基調構件1的表面和基體薄片2成爲同一面之薄片 層3。如此般，如第4圖及第8圖所示，藉由第1樹脂的射出 而使金屬基調構件1埋入基體薄片2，並在基體薄片2的背 面形成第1樹脂層25，藉此成形出具備薄片層3和第1樹脂 層2 5之一次成形品F 1。 〔形成第2模穴的步驟〕 如第5圖所示，在可動模具1 1A保持第1樹脂層25及薄 -19- 201116396 片層3的狀態下，使可動模具1 1A離開第1固定模具12後’ 讓旋轉平台15旋轉180度而使可動模具11Α位於與第2固定 模具1 3相對置的位置。然後，使旋轉平台1 5朝固定平台1 4 側移動而將可動模具11Α和第2固定模具13合模’如第3圖 所示，在被可動模具1 1 A ( 1 1 Β )所支承之一次成形品F 1 的薄片層3和第2固定模具13之間形成第2模穴22。這時， 在合模時藉由緊固具33的推壓而使滑動塊17往突出片2a側 滑動移動，以藉由滑動塊17和可動模具11A的一部分來挾 持固定突出片2a的緣部2b。 〔第2樹脂層的成形步驟〕 如第4圖及第9圖所示，從第2澆口 24將第2樹脂朝向第 2模穴22射出。亦即，第2樹脂是朝向薄片層3之金屬基調 構件1埋設側注入，而成形出第2樹脂層26。這時，薄片層 3是處於在基體薄片2內埋設金屬基調構件1的狀態，且基 體薄片2的表面和金屬基調構件1表面形成同一面。因此， 即使第2樹脂通過金屬基調構件1和基體薄片2的邊界面， 金屬基調構件1仍不會從基體薄片2剝離而能抑制金屬基調 構件1發生位置偏移的問題。 然後，如第5圖所示，讓旋轉平台1 5離開固定平台1 4 ，使可動模具11A ( 11B)和第2固定模具13開模。藉由該 開模，裝飾薄膜30的基體薄片30b會從裝飾部30a自然地剝 離，而獲得僅裝飾部30a轉印於第2樹脂的表面之二次成形 品（金屬基調裝飾樹脂成形品）F2。然後，將固化後的二 -20- 201116396[Technical Field] The present invention relates to a metal-based decorative resin molded article and a metal-based decorative resin molded article which are formed by composite molding of a plurality of resins sandwiching a metal-based decorative sheet. Production method. [Prior Art] A multilayer molded article in which an embedded sheet (hereinafter simply referred to as "decorative sheet") having a decorative layer is embedded between a plurality of resin layers is produced, for example, by the following steps. The first mold (cavity mold) and the second mold (first core mold) on which the decorative sheet is placed are clamped, and the first resin is formed on the first cavity formed between the first mold and the decorative sheet, and the decorative sheet is applied to the decorative sheet. One side forms a first resin layer. Next, in the state where the first resin layer and the decorative sheet are held by the first mold (cavity mold), another third mold (second core mold) and the first mold (cavity mold) are clamped to form a pair. The second resin is formed in the second cavity between the decorative sheet and the third mold (second core mold), and the second resin layer is formed on the other side of the decorative sheet. Thus, a resin molded article in which a decorative sheet is embedded between a plurality of resin layers is obtained (see Patent Document 1). According to the above-mentioned structure, the first resin layer and the second resin layer of the two-layered layer of the decorative sheet can be used for the resin layer on the front side in the first resin layer and the second resin layer of the multilayer molded article to be produced. The resin' can be seen through the pattern formed on the decorative sheet. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2005-668 No. 201116396. In the third embodiment, the decorative sheet 5 disposed between the first resin layer 8 and the second resin layer 9 of the multilayer molded article is For example, it is formed by laminating the vapor-deposited layer 6 and the base sheet 7. In this case, the vapor-deposited layer 6 is a layer to which a multilayer molded article is provided with a decoration. However, since the vapor-deposited layer 6 itself is very thin, it is difficult to impart a three-dimensional decoration to the multilayer molded article only by the vapor-deposited layer 6. Further, in the case where the shape of the multilayered product is complicated, the shape of the decorative sheet 5 must also be formed into a shape conforming to the multilayer molded article. Here, since the vapor-deposited layer 6 is very thin, there is a case where cracks (cracks) may occur in the vapor-deposited layer 6 because the shape of the multilayer molded article cannot be changed. Further, when the pattern, the characters, and the like applied to the vapor-deposited layer 6 are partially formed on the base sheet 7, if the shape of the multilayered molded article becomes complicated, the vapor-deposited layer 6 is stretched, and the deposited layer of the multilayered molded article is formed. The alignment work of the pattern of 6 or the like becomes difficult. The present invention is to provide a metal-based decorative resin molded article in which a metal-based sheet layer is disposed as an intermediate layer to enhance the decorative property, and a metal-based decorative resin molded article. The first characteristic structure of the metal-based decorative decorative resin molded article of the present invention comprises a sheet layer, a first resin layer, and a transparent second resin layer; the sheet layer has a base sheet and a metal-based member embedded on one side of the base sheet The first resin layer is formed on the other surface of the base sheet, and the second resin layer is formed by being superposed on the base sheet of the sheet layer and the metal base member. In this manner, since the metal-based member is disposed in a state of being embedded in the base sheet, for example, the thickness of the metal-based member can be increased to about 11,716,396 degrees. As a result, the resin molded article can be decorated with a three-dimensional metal-based member. Further, since the metal base member is disposed between the first resin layer and the second resin layer and the second resin layer is transparent, the surface pattern or the three-dimensional shape of the metal base member can be seen from the surface side of the resin molded article. In the second characteristic structure of the metal-based decorative resin molded article of the present invention, at least a part of the peripheral surface portion of the metal-based member is convex toward the front side, and the thickness is smaller as it is closer to the peripheral side. According to this configuration, the portion on the surface side of the peripheral surface portion of the metal-based member is convex, and the portion having a smaller thickness toward the peripheral side can reflect light from the outside. As a result, the stereoscopic feeling of the metal key member can be further increased when the resin molded article is viewed from the outside. In a third feature of the metal-based decorative resin molded article of the present invention, the sheet layer has a coating layer that cooperates with the base sheet to hold the metal-based member. According to this configuration, the metal-based member is reliably held by the base sheet and the coating layer, and the positional deviation of the metal-based member is less likely to occur during the resin molding. Therefore, it is possible to stably impart a decoration formed by a three-dimensional metal key member to the resin molded article. The first characteristic means of the method for producing a metal-based decorative decorative resin molded article of the present invention includes a step of attaching a metal-based member to one surface of the base sheet, and arranging the base sheet so that the metal-based member contacts the second mold In the step of the second mold, the first mold is clamped to the second mold, and the first mold hole for the first resin injection is formed between the base sheet disposed between the second mold and the first mold. a state in which the first resin is injected into the first resin in the first embodiment, and the base sheet is pressed against the second mold by the pressure of the first resin injected, and the metal base member is embedded in the base sheet. a step of molding the first resin layer on the side of the metal sheet on which the base sheet is not attached; and holding the first resin layer and the base sheet in the first mold, leaving the first mold The second mold molds the first mold and the other third mold, and forms a second cavity between the base sheet and the third mold. Steps of: forming step is carried out and the second resin layer of the second injection mold cavity in the second transparent resin. According to this characteristic means, when the second resin layer is injected and the second resin layer is formed, the metal base member is embedded in the base sheet. Even if the second resin passes through the metal base member, the metal base member is not subjected to the first 2 resin peeling. Further, since the metal-based member is placed in a state of being embedded in the base sheet, for example, the thickness of the metal-based member can be increased to about the thickness of the base sheet, and as a result, the resin-formed product which is decorated with the three-dimensional metal-based member can be produced. In addition, since the metal-based member is disposed between the first resin layer and the second resin layer and the second resin layer is transparent, a resin molded article having a pattern or a three-dimensional shape in which the surface of the metal-based member can be seen from the surface side can be produced. . Furthermore, since the metal-based member is disposed after the base sheet is formed, the stretching of the metal-based member such as the vapor-deposited layer caused by the formation of the base sheet does not occur, and the metal-based member and the base sheet are not formed. Will produce cracks. As a result, it is easy to arrange the metal-based member at a desired position of the resin molded article. -8 - 201116396 2 The first method of the creation of the French side is described as the front fat or the tree piece. The thin body is based on the upper part of the book. The BI is in the Ming dynasty. The product of the fat tree and the outside of the protrusion: the shape of the first description, υ τττ^ ΊΠΠ tree line decoration into the tune · 'substrate belongs to the golden dynasty: the formation of the resistance to the step The formation of the layered tree model 2 is described in the frontal surface of the pre-injection flow. According to this characteristic means, the second resin to be injected contacts the base sheet through the space surrounded by the protruding piece and the third mold. At this time, even if the high temperature second resin contacts the base sheet, the second resin is transferred. Since the heat of the base sheet is easily transmitted to the first mold through the protruding sheet to the base sheet, the base sheet is hard to be heated. Further, particularly in the case where the protruding piece is provided on the base sheet, the heat of the protruding piece conveyed from the second resin to the base sheet is first transmitted to the base sheet main body other than the protruding piece after being diffused in the width direction of the protruding piece. Therefore, the heat of the second resin is directly transmitted to the base sheet main body as compared with the case where the protruding piece is not provided, and the portion of the base sheet is not easily heated to a high temperature. Therefore, the melting of the base sheet and the deformation of the metal-based member (gate-area shifting) can be prevented. In particular, the portion near the protruding piece of the base sheet is liable to become high temperature, and the base sheet is easily melted, but the heat in the vicinity of the protruding piece can be transferred to the first mold by the protruding piece, whereby the melting of the base sheet can be appropriately prevented. . As a result, the phenomenon that the position of the metal-based member embedded in the base sheet is shifted can be suppressed. Further, according to this characteristic means, only the base sheet in which the metal base member is embedded is provided between the first resin layer and the second resin layer, and the heat of 201116396 of the second resin is transmitted to the first mold through the protruding piece. Thus, the amount of heat transferred to the first resin layer can be reduced, and the phenomenon that the first resin layer is remelted can be sufficiently prevented, and the thickness of the resin molded article can be sufficiently reduced. In the third characteristic means of the method for producing a metal-based decorative resin molded article of the present invention, in the step of molding the second resin layer, the second resin is injected while the edge of the protruding piece is fixed. According to this characteristic means, when the second resin is injected, the positional deviation of the base sheet can be avoided, and the floating and curling of the base sheet can be prevented. Thereby, the contact between the protruding piece and the first mold can be favorably maintained, and the heat of the base sheet can be surely transferred to the first mold by the protruding piece. Therefore, it is possible to surely prevent the base sheet from melting. As a result, it is possible to suppress the phenomenon in which the position of the metal key member buried in the base sheet is shifted. In a fourth aspect of the method for producing a metal-based decorative resin molded article of the present invention, in the step of molding the second resin layer, the flow path facing the protruding piece is connected along the second cavity. In the state, the resin is injected along the extending direction of the above-mentioned protruding piece. According to this feature, the second resin to be injected does not come into contact with the protruding piece and the main body portion of the base sheet, but flows smoothly along the portions of the base sheet to enter the second cavity. Therefore, compared with the structure in which the injected resin is in a frontal collision contact with the base sheet and enters the cavity, the possibility of precipitation of the resin in the vicinity of the base sheet is reduced, and the influence of the heat of the resin is not easy with the base sheet. As a result, the phenomenon that the position of the metal key member buried in the base sheet is shifted can be suppressed. -10-201116396 The fifth characteristic means of the method for producing a metal-based decorative resin molded article of the present invention, wherein the step of forming the second resin layer is the substrate sheet supported by the first mold and disposed on the first The second cavity is formed between the decorative films on the inner surface of the mold, and the fastening device (for fixing the decorative film to the third mold) is provided at a position in contact with the base end portion of the protruding piece. In the state, the resin is injected. According to this characteristic means, the decorative film is pressed against the third mold by the fastener before the position where the decorative film is to be assembled on the main portion of the final molded article, so that the decorative film can be suppressed from the third mold. A phenomenon in which the inner surface of the concave portion floats and a good quality molded article can be obtained. According to a sixth aspect of the method for producing a metal-based decorative resin molded article of the present invention, in the step of molding the second resin layer, the tip end of the protruding sheet formed on the base sheet is retracted to be provided in the first mold The resin is injected in the state of the stepped recess. According to this feature, the leading end of the protruding piece of the base sheet is protected by the recessed portion of the step, whereby the resin flow can be prevented from causing floating and "curling" of the base sheet, and a molded article of good quality can be obtained. In a seventh aspect of the method for producing a metal-based decorative resin molded article of the present invention, the metal-based member is used in such a manner that at least a part of the peripheral surface portion is convex toward the front side and a member having a smaller thickness toward the peripheral side is formed. When the second resin is injected, the second resin is injected so as to flow from the peripheral portion side having a small thickness toward the metal-based member. According to this characteristic means, the second resin is injected so as to flow from the peripheral portion side having a thickness of -11 - 201116396 degrees from the metal-based member to the metal-based member, so that the surface portion of the metal-based member and the second resin can be reduced. The generated frictional force can suppress the phenomenon in which the position of the metal-based member embedded in the base sheet is shifted. Further, the resin molded article produced has a convex shape on the surface side of the peripheral surface portion of the metal-based member, and a portion having a smaller thickness toward the peripheral side can reflect light from the outside. As a result, the stereoscopic feeling of the metal tone adjusting member can be further increased when the resin molded article is viewed from the outside. According to a eighth aspect of the invention, in the method of producing a metal-based decorative resin molded article of the present invention, after the metal-based member is attached to one surface of the base sheet, another resin is coated on the base sheet so as to cover the metal-based member. When the second resin is injected into the second cavity, if the surface portion of the metal-based member is exposed from the base sheet, the injected second resin flows through the surface portion of the metal-based member. In this case, a frictional force is generated between the surface portions of the second resin and the metal-based member, and the position of the metal-based member may be changed. However, according to the present feature, the surface portion of the metal-based member is protected by the coating. That is, when the second resin is injected into the second cavity, the second resin comes into contact with the coating layer, but does not contact the metal key member. As a result, the metal-based member does not directly act on the second resin to be injected, and the positional shift of the metal-based member in the resin molded article can be suppressed, and a resin molded article excellent in decorative properties can be produced. [Embodiment] -12 [First Embodiment] A metal-based decorative resin molded article F2 of the present invention and a method for producing the same will be described below. [Step of attaching the metal base member to the base sheet] The base sheet 2 is a resin molded body formed into a predetermined shape in advance, and the metal base member 1 is attached to the base sheet 2. The metal-based member 1 is a transfer-molded electroformed sheet, metal beads, or the like. Specifically, in the case where the metal-based member 1 is an electroformed sheet, the peeling paper on the back surface of the electroformed sheet is peeled off, and the portion of the base sheet 2 to be transferred is attached together with the film. The film was peeled off by gently rubbing the electroformed portion from above the film to fix it to the base sheet 2. As described above, the metal base member 1 is attached to the base sheet 2 as shown in Fig. 1. The step of attaching the metal-based member 1 to the base sheet 2 is performed after the base sheet 2 is formed into a predetermined shape, so that cracking does not occur in the metal-based member 1 as the shape of the base sheet 2 is changed. Further, by attaching the metal-based member 1 after the formation of the base sheet 2, the position of the metal-based member 1 on the resin-molded article can be naturally determined, and the alignment of the metal-based member 1 on the resin-formed article can be easily made. . Further, although various patterns may be formed on the base sheet 2, a plain color sheet which does not form a pattern may be used. The base sheet 2 may be composed of various resins such as an acrylic resin or a polyolefin resin, and when a resin such as a polycarbonate resin or a PET having high heat resistance is used, the base material is injected into the resin for secondary molding. The sheet 2 is remelted by the heat of the resin-13-201116396, which is a so-called "displacement near the gate" phenomenon. "Displacement near the gate" means that when the resin for secondary molding at a high temperature (2 5 (TC to 280 ° C) is in contact with the embedded sheet, the heat of the resin is transferred to the embedded sheet, and the heat is on the other hand. Since the heat-insulating effect of the primary molded article is not easily transmitted to the mold, the embedded sheet cannot be cooled by the mold and melted at a high temperature, and as a result, the pattern applied to the decorative layer flows and deforms. The thickness of the base sheet 2 It is preferably in the range of 7 5 to 2 0 0 μm, and is most easily used in the range of 125 to 150 μm. Next, a two-color molding die used in the production of the metal-based decorative resin molded article F2 will be described. The two-color molding die is set in two colors. The molding machine (only a part of which is shown) includes the movable molds 11Α and 11Β (both are examples of the first mold) and the first fixed mold 12 (an example of the second mold) as shown in FIGS. 2 to 5 . And a second fixed mold 13 (an example of a third mold). The two-color molding machine includes a fixed platform 14 and a rotary table 15 that is rotatable and movable forward and backward with respect to the fixed platform 14. The fixed platform 14 has a first fixed mold. 12 and the second fixed mold 13, the rotary table 15 has movable molds 11A and 11B. The movable molds 11A and 11'' are opposed to the first fixed mold I2 and the second fixed mold 13 respectively. According to this structure, as shown in Fig. 3 When the rotary table 15 is pressed against the fixed platform 14, the movable molds 11A, 11A and the first fixed mold 1 2 and the second fixed mold 13 can be simultaneously clamped, and the first resin can be simultaneously injected and the second resin can be simultaneously molded. As shown in Fig. 2, in the state before the mold clamping, the movable mold 对 opposed to the second fixed mold 13 is held by the first step 14 - 201116396 shaped product F1 ( The first resin layer 25 and the sheet layer 3). On the other hand, the base sheet 2 used for the subsequent primary molding is held on the first fixed mold 12. The two-color molding machine is provided to provide the base sheet 2 in the base sheet 2 The robot device 16 on the first fixed mold 12. The second fixed mold 13 is provided with a film feeding device 31 for feeding a decorative film (transfer box) 30, and a winding device 32 for winding the decorative film 30. Pressing the decorative film 30 against the movable mold 1 1 A, 1 1B side The rectangular frame-shaped fastening material 33. The decorative film 30 is formed by integrating the decorative portion 30a welded to the second resin layer 26 and the base sheet 30b for operation, and is transferred to the second resin layer in the decorative portion 30a. The base sheet 30b is peeled off at any step after the step 26. The decorative portion 3〇a generally has a peeling protective layer which is finally the outermost layer of the multilayer molded article, and an adhesive layer welded to the resin layer, generally in the peeling protection. A pattern layer is provided between the layer and the adhesive layer. As the material of the base sheet, for example, a polypropylene resin, a polystyrene resin, a polyamide resin, a polyester resin, an acrylic resin, or a polyvinyl chloride resin can be used. A resin sheet such as a resin; a metal foil such as an aluminum foil or a copper foil; a cellulose paper such as a cellophane, a coated paper, or a celluloid, or the like, or a laminate thereof. Further, in order to improve the releasability of the base sheet 30b, a release layer composed of an amine-based alkyd resin may be formed between the base sheet 30b and the decorative portion 30a. The thickness of the base sheet 30b is preferably 5 to 500 μm. The material of the peeling protective layer is, for example, an acrylic resin, a polyester resin, a polyvinyl chloride resin, a cellulose resin rubber resin -15-201116396, a urethane resin, a polyvinyl acetate resin, or the like. A copolymer such as a vinyl chloride-vinyl acetate copolymer resin or an ethylene-vinyl acetate copolymer resin can be used. When the protective layer is required to have a hardness, a photocurable resin such as an ultraviolet curable resin, a radiation curable resin such as an electron beam curable resin, or a thermosetting resin may be selected. For the adhesive layer, a material having a high affinity with the resin to be welded should be selected. For example, when the material of the material to be transferred is an acrylic resin, an acrylic resin can be used. Further, when the material to be transferred is a polyphenylene ether, a polystyrene resin, a polycarbonate resin, a styrene copolymer resin, or a polystyrene resin, affinity with the resins can be used. Acrylic resin, polystyrene resin, polyamine resin or the like. Further, when the material of the resin molded article is a polypropylene resin, a chlorinated polyolefin resin, a vinyl chloride-vinyl acetate copolymer resin, a cyclized rubber, or a coumarone-indene resin can be used. The thickness of the adhesive layer should be 0.5 to 50 μm. The two-color molding die may have a structure in which the metal base member 1 can be embedded in the base sheet 2, and the structure in which the decorative film 30, the film feeding device 31, the film winding device 32, and the fastening tool 33 are not provided is not provided. A problem has occurred. Further, the first resin and the second resin may be resins of different colors, or may be resins having different properties such as hardness. For example, the first resin is an alloy resin using a polycarbonate resin, an ABS resin or a polycarbonate resin and an ABS resin, and the second resin is ruthenium (polymethyl methacrylate resin). In particular, when the first resin is ABS resin and the second resin is PA AM, the moldability of the ABS resin is high. It can be well-formed -16- 201116396 Multi-layer molding such as two-color molding. Further, even if the softening temperature of the ABS resin is lower than the softening temperature of the PMMA, the presence of the base sheet 2 can suppress the deformation of the formed ABS resin by the heat of the PMMA resin when PMMA is injected. The movable molds 11A and 11B are provided with a sliding block 17 for fixing a part of the base sheet 2 (an example of a fixing means) and a substantially rectangular recess 18 for accommodating the fastening tool 33 at the time of mold clamping. The detailed structure of these is shown in Figures 6 and 9. As shown in Fig. 10 (showing the secondary molded product F2 removed from the movable molds 11A and 11B after curing), the edge portion 2b of the trapezoidal protruding piece 2a is formed on one side of the base sheet 2, and the edge portion 2b is formed by the aforementioned The slider 17 is fixed. Further, in the movable mold 11B, the auxiliary mold hole 22A of the protruding piece 2a can be accommodated when the second fixed mold 13 and the movable mold 1 1B are closed. Further, the second gate 24 for injecting the second resin is provided at a position where the second resin must pass through the auxiliary cavity 22A to be injected into the second cavity 22. More specifically, when the movable mold 11B and the second fixed mold 13 are closed, a communication passage 40 for allowing the second gate 24 and the second cavity 2 2 to communicate with each other is formed therebetween. The second resin injected from the second gate 24 is injected into the second cavity 22 via the communication passage 4〇. The communication passage 40 includes a linear first communication portion 4 1 that reaches the vicinity of the fastening tool 3 3 from the second gate 24, and a substantially C-shaped second communication that is bypassed around the fastening tool 33. The portion 42 is directed from the second communication portion 42 and faces the auxiliary cavity 22A of the distal fastening tool 33. As shown in Fig. 6, the auxiliary cavity 22A which can accommodate the protruding piece 2a is formed to be wider as it is closer to the primary molded product F1. As a result of the formation of the communication passage 40 as described above, when the second resin is injected, -17-201116396 can always allow the second resin to come into contact with the base sheet 2 through the space surrounded by the protruding piece 2a and the second fixed mold 13. Therefore, even if the high temperature second resin contacts the base sheet 2, the heat of the second resin is transferred to the base sheet 2'. The heat received by the base sheet 2 can be transmitted through the large-area protruding sheet 2a to the movable mold 11B (11A). The heat is dissipated, so that the base sheet 2 does not become excessively high in temperature, and the base sheet 2 is prevented from being melted. Further, at the time of mold clamping, the fastening tool 33 pushes the slider 17 toward the protruding piece 2a side to slide it to move the edge portion 2b of the fixing protruding piece 2a by the sliding block 17 and the movable mold 11B. Therefore, the phenomenon in which the positional displacement of the base sheet 2 occurs can be prevented when the second resin is injected. Thereby, since the contact between the protruding piece 2a and the movable mold 11B can be favorably maintained, the heat of the base sheet 2 can be surely transmitted to the movable mold 11B through the protruding piece 2a, and the heat of the edge portion 2b of the protruding piece 2a can be surely The heat is efficiently dissipated to the movable mold 1 1 B and the slide block 17 . Thus, the melting of the base sheet 2 can be surely prevented, and the phenomenon in which the position of the metal-based member 1 embedded in the base sheet 2 is displaced can be suppressed. Further, it is possible to prevent the floating and "curling" of the base sheet 2, and to manufacture a multilayer molded article. In the following, a method of producing a metal-based decorative multilayer molded article in which a base sheet 2 to which a metal base member 1 is attached is sandwiched between a plurality of resin layers will be described. [Step of arranging the base sheet] As shown in Fig. 2, the base of the metal-based member 1 is attached using the robot device 16 in a state where the movable mold i a and the second fixed mold 12 are opened. The sheet 2 is provided in the first fixed mold 12. Here, the metal base member 1 attached to the base thinner -18-201116396 sheet 2 is placed on the base sheet 2 so as to be in contact with the first fixed mold 12, and the base sheet 2 is attracted to the first fixed mold I2. The device (not shown) is held. [Step of Forming First Cavity] As shown in FIG. 3, the rotary table 15 is moved toward the fixed stage 14 side, and the movable mold 1 1A is clamped with respect to the first fixed mold 12, and the first mold is fixed. A first cavity 2 1 is formed between the base sheet 2 supported by the fixed mold 12 and the movable mold 丨丨A. [Step of Forming the First Resin Layer] As shown in Fig. 7, the first resin is ejected from the first gate 2 3 toward the first cavity 2 1 . When the first resin is injected into the first cavity 2, the base sheet 2 is pressed against the first fixed mold 12 by the pressure of the injected first resin. At this time, in the vicinity of the metal-based member 1, the base sheet 2 is stretched in conformity with the shape of the metal-based member 1, and the metal-based member 1 is buried in the base sheet 2, whereby the surface of the metal-based member 1 and the base sheet are formed. 2 becomes the sheet layer 3 of the same side. As described in FIGS. 4 and 8 , the metal base member 1 is embedded in the base sheet 2 by the first resin, and the first resin layer 25 is formed on the back surface of the base sheet 2 to form the first resin layer 25 . The primary molded product F 1 having the sheet layer 3 and the first resin layer 25 is provided. [Step of Forming the Second Cavity] As shown in Fig. 5, the movable mold 1 1A is moved away from the first fixed mold while the movable mold 1 1A holds the first resin layer 25 and the thin -19-201116396 sheet 3 After 12', the rotary table 15 is rotated by 180 degrees, and the movable mold 11 is placed at a position facing the second fixed mold 13. Then, the rotary table 15 is moved toward the fixed stage 14 side to mold the movable mold 11 and the second fixed mold 13 as shown in Fig. 3, and is supported by the movable mold 1 1 A (1 1 Β ). The second cavity 22 is formed between the sheet layer 3 of the primary molded product F 1 and the second fixed mold 13 . At this time, the slide block 17 is slidably moved toward the protruding piece 2a side by the pressing of the fastening tool 33 at the time of mold clamping to grip the edge portion 2b of the fixed protruding piece 2a by the sliding block 17 and a part of the movable mold 11A. . [Step of Forming Second Resin Layer] As shown in Figs. 4 and 9, the second resin is ejected from the second gate 24 toward the second cavity 22. That is, the second resin is injected toward the embedding side of the metal-based member 1 of the sheet layer 3, and the second resin layer 26 is formed. At this time, the sheet layer 3 is in a state in which the metal-based member 1 is embedded in the base sheet 2, and the surface of the base sheet 2 and the surface of the metal-based member 1 form the same surface. Therefore, even if the second resin passes through the boundary surface between the metal-based member 1 and the base sheet 2, the metal-based member 1 does not peel off from the base sheet 2, and the problem of positional displacement of the metal-based member 1 can be suppressed. Then, as shown in Fig. 5, the rotary table 15 is moved away from the fixed stage 14 to mold the movable mold 11A (11B) and the second fixed mold 13. By the mold opening, the base sheet 30b of the decorative film 30 is naturally peeled off from the decorative portion 30a, and a secondary molded article (metal-based decorative resin molded article) F2 in which only the decorative portion 30a is transferred onto the surface of the second resin is obtained. . Then, after curing, the second -20- 201116396

調構件1被注入的樹脂推壓，而能抑制位置偏移的發生。 此外，構成輔助模穴22A的結果’在注入第2樹脂時’ -21 - 201116396 第2樹脂會通過第1連通部41、第2連通部42、輔助模穴22A 才開始接觸基體薄片2。因此，即使高溫的第2樹脂接觸薄 片層3而將第2樹脂的熱傳送至薄片層3，薄片層3所承受的 熱可透過突出片2a而有效地往可動模具11B ( 11A)散熱。 結果，薄片層3不致變得過度高溫，而防止薄片層3發生熔 融，且能抑制金屬基調構件1之熔融及位置偏移等。 〔第2實施形態〕 第2實施形態所使用之成形用模具，如第1 1圖〜第1 6圖 所示係具備：可動模具5 1 A、5 1 B (第1模具的一例）、以 及第1固定模具52 (第2模具的一例）和第2固定模具53 ( 第3固定模具的一例）。第11圖〜第16圖係顯不將第1樹脂 和第2樹脂注入後的狀態。在第2實施形態的例子，僅使用 埋設有金屬基調構件1之基體薄片2’並未使用裝飾薄膜30 。雖未圖示出，與上述實施形態同樣的，可動模具5 1 A、 51 B是被旋轉平台1 5所支承，第1固定模具52和第2固定模 具53是被固定平台14所支承。 若保持著基體薄片2之第1固定模具52和可動模具51A 合模，會在基體薄片2和可動模具5 1 A之間形成第1模穴2 1 。第12圖及第13圖係顯示’對該第1模穴21注入第1樹脂而 獲得一次成形品F 1的狀態。另一方面，若相對於第2固定 模具5 3，將保持著經由上一步驟注入/成形之一次成形品 F1的可動模具51B合模，在一次成形品F1的基體薄片2和第 2固定模具53之間會形成第2模穴22。第15圖及第16圖係顯 -22- 201116396 示，對該第2模穴22注入第2樹脂而獲得二次成形品F2的狀 態。如第1 6圖所示，在可動模具5 1和第2固定模具5 3之間 ，形成可收容基體薄片2的突出片2a之輔助模穴71 ’用來 注入第2樹脂之第2澆口 66，是設置在第2樹脂一定要通過 輔助模穴71才能注入第2模穴22的位置。 如第11圖所示，基體薄片2的突出片2a’是從基體薄 片2之一側的長邊大致整個範圍突出而呈長方形。如第11 圖的XII-XII截面（第12圖）所示，在可動模具51A的分模 面5 1 a和凸部5 1 b之間，沿著凸部5 1 b的一個長邊形成截面V 字狀的溝槽63。另一方面，在第1固定模具52的分模面 和凹部52b之間，形成可嵌入溝槽63之截面V字狀的突條62 。因此，若可動模具51A和第1固定模具52合模’突條62的 一側面6 2 a會接觸溝槽6 3的一側面6 3 a，同時藉由突條6 2的 另一側面62b (按壓部的一例）和溝槽63的另一側面63b ( 按壓部的一例）來挾持基體薄片2的突出片2a。 如第η圖、第12圖、第11圖的χιιι-χπι截面（第I3圖 )所示，若可動模具51A和第1固定模具52合模，在可動模 具51 A和第1固定模具52之間，會形成讓第1澆口 57和第1模 穴21連通之第1連通流路61。從第U堯口 57射出的第1樹脂 ，經由該第1連通流路6 1而注入第1模穴2 1。第1連通流路 61係具備：形成於第1可動模具51 A的分模面51a和第1固定 模具5 2的分模面5 2 a間之直線狀的第1連通部5 8、形成於突 條62的一側面62a和溝槽63的一側面63a間之直線狀的第2 連通部59、以及形成於突條62的另一側面62b和溝槽63的 -23- 201116396 另一側面63b間之第3連通部60。第3連通部60，是從第2連 通部59朝向一次成形品F1變寬，而呈漸寬狀。第2連通部 59相對於第1連通部58呈彎折狀連接，第3連通部60相對於 第2連通部59呈彎折狀連接。 另一方面，如第14圖之XV-XV截面（第1 5圖）所示， 在第2固定模具53的分模面53 a和凹部53b之間，形成可嵌 入溝槽63之V字狀的突條72 »因此，若可動模具51B和第2 固定模具53合模，突條72的一側面72a會接觸溝槽63的一 側面63a，同時藉由突條72的另一側面72b (按壓部的一例 )和溝槽63的另一側面63b (按壓部的一例）來挾持基體 薄片2的突出片2a。 如第14圖、第15圖、第14圖的XVI-XVI截面（第16圖 )所示，若可動模具51B和第2固定模具53合模，在可動模 具51 B和第2固定模具53之間，會形成讓第2澆口 66和第2模 穴22互相連通之第2連通流路70 »從第2澆口 66射出的第2 樹脂，經由該第2連通流路70而注入第2模穴22。第2連通 流路70係具備：形成於第2可動模具51B的分模面51a和第2 固定模具53的分模面53 a間之直線狀的第1連通部67、形成 於突條72的一側面72a和溝槽63的一側面63 a間之直線狀的 第2連通部68、以及形成於突條72的另一側面72b和溝槽63 的另一側面63b間之第3連通部69。第3連通部69，是從第2 連通部68朝向一次成形品F1變寬，而呈漸寬狀。第2連通 部68相對於第1連通部67呈彎折狀連接，第3連通部69相對 於第2連通部68呈彎折狀連接。在突條72的另一側面72b和 -24- 201116396 溝槽6 3的另一側面6 3 b間，形成可收容基體薄片2的突出片 2a的一部分之輔助模穴71。在此’讓基體薄片2的突出片 2 a的一部分露出之第3連通部69是構成輔助模穴71。 如此般構成連通流路70的結果’在注入第2樹脂時’ 始終能讓第2樹脂通過輔助模穴71附近的突出片2a和第2固 定模具53所包圍的空間才接觸基體薄片2。因此’即使高 溫的第2樹脂接觸基體薄片2而將第2樹脂的熱傳送至基體 薄片2，基體薄片2所承受的熱可透過大面積的突出片2a而 有效地往可動模具51B(51A)散熱，因此基體薄片2不致 變得過度高溫，而防止基體薄片2發生熔融。結果’可抑 制埋設於基體薄片2之金屬基調構件1的位置發生偏移的現 象。 而且，在合模時，如第11圖及第12圖所示，突出片2a 之未重疊於第3連通部60之兩側部分2c、2d，被挾持固定 在可動模具5 1 A和第1固定模具52之間。因此，從第1澆口 57將第1樹脂注入第1模穴21而在基體薄片2的下面進行第1 樹脂層25的成形時，第1樹脂不致進入與另一側的側面62b 間的間隙。 此外，關於第2固定模具5 3和可動模具5 1 B也是，如第 14圖及第15圖所示，突出片2a之未重疊於第3連通部69之 兩側部分2f、2g，被挾持固定在可動模具（51B) 51A和第 2固定模具53之間。因此，將從第2澆口 66射出的第2樹脂 注入第2模穴22而在基體薄片2的金屬基調構件1埋設側進 行第2樹脂層2 6的成形時，第2樹脂不致進入與另一側的側 -25- 201116396 面63b間的間隙。 然後，將可動模具51B和第2固定模具53開模’將二次 成形品F2從可動模具5 1 B取下。又作爲精加工’是將從可 動模具（5 1 B ) 5 1 A取下後的二次成形品F2之突出外部的 突出片2a、第1樹脂層25及第2樹脂層26的突出部分切斷（ 參照第17圖）。這時，由於從二次成形品F2之一側長邊’ 突出片2a、第1樹脂層25及第2樹脂層26的突出部分是形成 突出的，因此只要進行一次切斷即可，而能謀求減少步驟 及生產性提昇。此外，由於是藉由可動模具51A及第1固定 模具52、可動模具51B和第2固定模具53來挾持突出片2a’ 因此不須另外設置用來挾持突出片2 a的構造’而能謀求構 造簡單化。再者，設置複數個澆口而取出複數個成形品亦 可。 〔第3實施形態〕 以下之第20圖〜第27圖所示的第3實施形態，主要是針 對與第1實施形態的構造不同的構造作說明，關於相同構 造則省略其說明。第3實施形態所使用之成形用模具，如 第20圖所示係具備：被固定平台14支承的第1固定模具182 (第2模具的一例）和第2固定模具183 (第3模具的一例） 、以及被旋轉平台1 5支承的可動模具1 8 1 A、1 8 1 B (第1模 具的一例）。旋轉平台15相對於固定平台14可旋轉且能進 退。在此，固定模具182、183是凹狀的母模具，一對可動 模具181A、181B是凸狀的公模具。如第20圖所示，在第1 -26- 201116396 固定模具182的凹部，卡止著貼附有金屬基調構件1之基體 薄片2 ;在第2固定模具184的凹部配置裝飾薄膜30，而能 藉由緊固具33進行固定。另一方面，在第2可動模具181B 的凸部卡止著上一步驟所製得的一次成形品F 1。該一次成 形品F 1與第22圖所示的一次成形品F 1具有相同的形狀。 接著，如第21圖所示，若將旋轉平台15朝向固定平台 1 4按壓，第1固定模具182和可動模具1 81 A會合模，同時第 2固定模具1 83和可動模具181B會合模》 若第1固定模具182和可動模具1 81 A合模，如第21圖的 上部所示，在卡止於第1固定模具182之基體薄片2和第1可 動模具1 8 1 A之間，會形成用來收容第1樹脂之第1模穴2 1。 只要在第1模穴21注入第1樹脂，第1樹脂就會熔接在基體 薄片2的內面，而獲得埋設有金屬基調構件1之基體薄片2 (薄片層3 )和第1樹脂層2 5所構成的一次成形品F 1。第2 1 圖係顯示注入第1樹脂後的狀態。 另一方面，如第21圖的下部所示，若第2固定模具183 和可動模具181B合模，在卡止於可動模具181B之一次成形 品F 1和卡止於第2固定模具1 8 3之裝飾薄膜3 0之間，會形成 第2模穴22，而將第2樹脂注入其中。實際上，在注入第2 樹脂之前，裝飾薄膜30是被吸附在第2固定模具183之凹部 的內面。爲了實現此吸附，在第2固定模具1 83的凹部設有 :多數個微細的吸引孔（未圖示）、爲了透過吸引孔而使 第2固定模具183的凹部內面產生負壓之減壓泵（未圖示） 。這種吸附機構也設置在第1固定模具1 82上。 -27- 201116396 如第21圖的主要部分的放大圖（第24圖及第25圖）所 示，在基體薄片2形成兩個突出片。其中之一，是從基體 薄片2之四邊緣部的一部分呈直線狀延伸的第1突出片2A。 另一個，是從相反側的一部分往外彎曲形成之第2突出片 2B。在第20圖及第21圖所示的成形步驟之間’第1突出片 2A和第2突出片2B都被按壓在第1固定模具182的內面’此 外，在最終的二次成形品F2是將突出片2A、2B切除。 如第25圖所示，第1突出片2A，當第2固定模具183和 可動模具181B合模時，是被收容在形成於可動模具181 B之 第1輔助模穴136a。又用來注入第2樹脂之第2澆口 139，是 設置在.第2樹脂一定要通過設有第1突出片2A之輔助模穴 136a的區域才能注入第2模穴22的位置。又如第24圖所示 ，第2突出片2B，當第1固定模具182和可動模具181 A合模 時，是被收容在形成於可動模具181A之第2輔助模穴132a 的一部分。 若第2 1圖的步驟所注入的第1樹脂及第2樹脂之固化結 束’如第22圖所示，使旋轉平台15脫離固定平台14，而將 可動模具181A、181B分別從第1固定模具182、第2固定模 具183進行開模。在此狀態下，是在第1可動模具181A的凸 部支承所成形的一次成形品F1，在第2可動模具181B的凸 部支承所成形的二次成形品F 2。將二次成形品F 2從第2固 定模具183取出，如第23圖所示，讓旋轉平台15旋轉180度 ，而變成能反覆進行第20圖起的步驟。對於所取出的二次 成形品F2’進行突出片2A、2B的切除操作等的處理。 -28- 201116396 在此，重新對第20圖及第2 1圖的步驟作詳細的說明。 首先，如第21圖及第24圖所示，若第1固定模具182和 可動模具181 A合模，在兩模具182、181A之間會形成讓第 1澆口 138和第1模穴21互相連通的連通流路140。連通流路 1 40係具備：與第1澆口 1 3 8的出口直接連通之直線狀的第1 連通部1 40A、與第1模穴2 1的出口直接連通之直線狀的第2 連通部140B。第2連通部140B和第1連通部140A是彼此大 致平行地延伸，且互相連結成曲柄狀。在相當於其連結邊 界之第1固定模具1 82的內面，沿著第1樹脂的進入方向形 成朝固定平台1 4側階梯狀地凹陷之退縮部1 8 2X。而且，將 基體薄片2之第2突出片2B的前端，以能被該退縮部182X按 壓的方式進行對置，藉此，可防止第1樹脂流造成基體薄 片2之浮動和「捲曲」等。退縮部182X的深度超過基體薄 片2的厚度。 接著，如第21圖及第25圖所示，若第2固定模具183和 可動模具1 8 1 B合模，在兩模具1 8 3、1 8 1 B之間會形成讓第2 澆口 1 3 9和第2模穴22互相連通的連通流路1 42。連通流路 142是由第2輔助模穴136a所形成，係具備：從第2澆口 139 出發而到達附近的緊固具33之直線狀的第1連通部I42 A、 沿著緊固具3 3的下方側面3 3b而以接近旋轉平台1 5的方式 進入之第2連通部142B、沿著緊固具33的上面33c而朝圖的 上方延伸之第3連通部142C、沿著緊固具33的上方側面33d 而靠近第2固定模具183之第4連通部142D。 屬於連通流路142的最終部位之第4連通部142D，由於 -29- 201116396 朝向第2固定模具183而沿著圖的大致橫向延伸，在第2固 定模具183和可動模具181B的邊界面，第4連通部142D的終 端部（面向突出片之流路部位的一例）和第2模穴22的入 口部彼此會以無角度的方式大致直線狀地連接。具體而言 ，第25圖所示之緊固具33之圖中的上方側面33d之基端部 ，與最終二次成形品F2的端面位置是在S點形成一致。 在第4連通部142D，沿著第2樹脂的進入方向形成朝可 動模具181B的中心線階梯狀地凹陷之退縮部142X (段差狀 凹部之一例）。而且，將基體薄片2之第1突出片2A的前端 ，以能被該退縮部142 X按壓的方式進行對置，藉此，可防 止第2樹脂流.造成基體薄片2之浮動和「捲曲」等。退縮部 1 42 X的深度超過基體薄片2的厚度。 如此般構成連通流路142的結果，在注入第2樹脂時， 始終能讓第2樹脂通過第1突出片2A和緊固具33所包圍的空 間才接觸第2模穴22內的基體薄片2。因此，即使高溫的第 2樹脂接觸基體薄片2而將第2樹脂的熱傳送至基體薄片2， 基體薄片2所承受的熱可透過沿著第2樹脂的進入方向變寬 之漸寬狀的突出片2A而有效地往可動模具181B散熱，因此 第2模穴22內的基體薄片2不致變得過度高溫，而防止組裝 於最終二次成形品F2之基體薄片2的主體部位發生熔融及 金屬基調構件1的變形等。此外，由於第1突出片2A形成漸 寬的形狀，即使從第2樹脂傳送至基體薄片2的第1突出片 2A的熱，先沿著第1突出片2A的寬度方向擴散後才傳送至 第1突出片2A以外的基體薄片2，仍能防止基體薄片2的局 -30- 201116396 部成爲高溫的現象。結果，可抑制埋設於基體薄片2之金 屬基調構件1的位置發生偏移的現象。 此外，如前述般，由於第4連通部142D的終端部第2模 穴22的入口部彼此以無角度的方式大致直線狀地連接，在 第2樹脂層的成形步驟從第2澆口 139注入的第2樹脂，是在 面向第1突出片2A之第4連通部1UD沿著第2模穴22連接的 狀態下，沿著第1突出片2 A的延伸方向注入。亦即，這時 的第2樹脂，對於基體薄片2之第1突出片2A及組裝於最終 二次成形品F2的主體部位，不是進行正面碰撞的接觸，而 是沿著基體薄片2之主體部位順利流過而進入第2模穴22。 因此，相較於從第2澆口 139注入的樹脂是與基體薄片2進 行正面碰撞接觸而進入第2模穴22的構造，第2樹脂在基體 薄片2的附近發生沉澱的可能性減低，第2樹脂之熱的影響 不容易及於基體薄片2。 再者，如前述般，第25圖所示之緊固具33之圖中的上 方側面33d之基端部，是與最終二次成形品F2的端面位置 一致。亦即，裝飾薄膜3 0，在最終二次成形品F2之主體部 分上要組裝裝飾薄膜30的部位之前方位置爲止’是藉由緊 固具33按壓在第2固定模具183上’因此可抑制裝飾薄膜30 從第2固定模具183的凹部內面上浮的現象。 〔第4實施形態〕 如第26圖所示，作爲貼附於基體薄片2上之金屬基調 構件1是採用：其周緣表面部1 A的一部分朝表面側呈凸狀 -31 - 201116396 ，且形成越靠近周緣側厚度越小的構件。而且’如第2 7圖 所示，在二次成形時，是以從金屬基調構件1之厚度小的 周緣部側朝向金屬基調構件1流動的方式將第2樹脂注入。 如此，可減少金屬基調構件1的表面部和第2樹脂接觸所產 生的摩擦力，而能抑制薄片層3之金屬基調構件1的位置發 生偏移的現象。此外，相較於金屬基調構件1的側部呈垂 直平面狀的情況，由於側部的表面積變大，在從外部觀察 樹脂成形品時可進一步增加金屬基調構件1的立體感。 〔第5實施形態〕 如第28圖所示，在基體薄片2的一面貼附金屬基調構 件1之後，以覆蓋金屬基調構件1的方式在基體薄片2上被 覆其他的樹脂。如此般，藉由在金屬基調構件1的表面也 設置被覆層4，如第29圖所示，在注入第2樹脂時，薄片層 3的金屬基調構件1可藉由被覆層4保護，能進一步防止薄 片層3的金屬基調構件1發生位置偏移。被覆層4可使用各 種樹脂，但較佳爲使用與第2樹脂相同的樹脂。如此，將 被覆層4和由第2樹脂成形出的第2樹脂層26—體化，從樹 脂成形品（金屬基調裝飾樹脂成形品）F2的外部觀看時， 可減低被覆層4對金屬基調構件1的美觀造成的影響。 〔其他實施形態〕 (1 )在上述各實施形態所例示的構造，是對於用來 保持第1樹脂層25和基體薄片2之可動模具（第1模具的一 -32- 201116396 例），讓形成於基體薄片2之突出片接觸，且透過突出片 和與可動模具（第1模具的一例）組合之第2固定模具（第 3模具的一例）所包圍的空間來注入第2樹脂。然而，亦可 取代此構造，在第1樹脂層25形成突出二次成形品F2外部 之突出片，對於用來保持第1樹脂層25和基體薄片之可動 模具（第1模具的一例），讓第1樹脂層2 5之突出片接觸， 且透過突出片和與可動模具（第1模具的一例）組合之第2 固定模具（第3模具的一例）所包圍的空間來注入第2樹脂 〇 (2 )如第3 0圖所示，使第2模穴22的寬度（相當於金 屬基調裝飾樹脂成形品之第2樹脂層2 6的厚度）比第1樹脂 層25的厚度更大亦可。例如，基體薄片2的厚度如前述般 爲75〜200 μπι，第1樹脂層25的厚度爲0.6〜1.2 mm的情況， 使第2模穴22的寬度（相當於第2樹脂層26的厚度）比第1 樹脂層25的厚度更大。如此，當第2樹脂通過埋設於基體 薄片2之金屬基調構件1上時，金屬基調構件1所產生的剪 切應力變小。結果，作用於金屬基調構件1之第2樹脂流動 方向的力量變小，金屬基調構件1不容易從基體薄片2之埋 設位置偏移。 (3 )在上述實施形態所示的構造，是使用裝飾薄膜 3 0 (轉印箔）而在第2樹脂層2 6的表面轉印裝飾部3 0 a，但 亦可取而代之的，將素地的基體薄片或在基體薄片上賦予 模樣等而成的嵌入薄片直接形成一體化，或做成不使用裝 飾薄膜30及嵌入薄片的構造。又裝飾薄膜30亦可爲薄片狀 -33- 201116396 ，嵌入薄片亦可爲薄膜狀。 (4 )在第1實施形態所例示的構造’固定手段是挾持 基體薄片2的緣部2b之滑動塊17，但並不限定於這樣的構 造，例如固定手段亦可爲吸引緣部2b之吸引手段。 (5 )在上述實施形態所例示的多層成形機，係具備 旋轉平台15和固定平台14。該旋轉平台15，係具有兩個可 動模具（第1模具的一例），可朝橫方向進退且可繞沿橫 方向的軸芯旋轉；該固定平台14，係具有第1固定模具（ 第2模具的一例）及第2固定模具（第3模具的一例）。然 而並不限定於這樣的多層成形機，例如，一次成形是進行 第1模具和第2模具的合模，二次成形，是讓可前進後退地 設置在第2模具內的滑動模具（第3模具的一例）後退而在 其與第1模具間形成第2模穴，並對該第2模穴射出第2樹脂 亦可。此外也能使用：具備第1可動平台及第2可動平台之 多層成形機；該第1可動平台，係具有可動模具（第1模具 的一例）且能在上下方向進退；該第2可動平台，係具有 第1固定模具（第2模具的一例）及第2固定模具（第3模具 的一例）且能在橫方向滑動。又能使用：具備可動平台及 旋轉平台之多層成形機；該可動平台，係具有可動模具（ 第1模具的一例）且能在橫方向進退；該旋轉平台，是將 第1固定模具（第2模具的一例）及第2固定模具（第3模具 的一例）背對背地安裝，且能繞給直軸旋轉。 (6 )作爲第2實施形態的變形例，例如第丨8圖、第i 9 圖所示’在可動模具5 1的分模面5 1 a和凸部5 1 b之間形成可 -34- 201116396 動模具5 1側的傾斜部7 3

article (metal-based decorative resin molded article) F2 is removed from the movable mold 11A (1 1B ). Then, after the rotary table 15 is rotated by 180 degrees, the movable mold iiB and the second fixed mold 13 are opposed to each other, and the resin is injected from the second gate 24 of the second fixed mold 13 to perform secondary molding. The mold 1 1 A faces the first fixed mold 12, and the resin is injected from the first gate 23 of the first fixed mold 12 to perform primary molding. By repeating the above operation, a secondary molded article (metal-based decorative resin molding) in which the decorative portions 30a of the first resin layer 25, the sheet layer 3, the second resin layer 26, and the decorative film 30 are sequentially laminated is produced. Product) F2. Further, as a finishing step, the protruding piece 2a protruding outside the secondary molded article (metal-based decorative resin molded article) F2 is cut (see Fig. 10). In the case of manufacturing a multilayer molded article (the metal base member 1 is disposed between the two resin layers), the metal base member 1 is first attached to the base sheet 2, and the metal base member 1 is buried at the time of primary molding. The sheet layer 3 is formed on the base sheet 2, and the resin layers on both sides of the sheet layer 3 are formed. As described above, in the case where the decorative layer is formed by using a vapor deposition layer or the like, the metal base member 1 having a relatively large thickness can be applied to the decoration to impart a three-dimensional decoration to the multilayer molded article. Further, the sheet layer 3' is formed in a state in which the metal-based member 1 is embedded in the base sheet 2, even when the resin is implanted toward the metal-based member 1 of the sheet layer 3, because the injected resin passes through the metal-based member 1. The upper portion prevents the metal-based member 1 of the sheet layer 3 from being pressed by the injected resin, and the occurrence of positional deviation can be suppressed. Further, the result of forming the auxiliary cavity 22A is "when the second resin is injected" -21 - 201116396 The second resin comes into contact with the base sheet 2 through the first communication portion 41, the second communication portion 42, and the auxiliary cavity 22A. Therefore, even if the high temperature second resin contacts the sheet layer 3 and transfers the heat of the second resin to the sheet layer 3, the heat received by the sheet layer 3 can be efficiently transmitted to the movable mold 11B (11A) through the protruding sheet 2a. As a result, the sheet layer 3 does not become excessively high in temperature, and the sheet layer 3 is prevented from being melted, and melting, positional shift, and the like of the metal-based member 1 can be suppressed. [Second Embodiment] The molding die used in the second embodiment includes the movable molds 5 1 A and 5 1 B (an example of the first mold) as shown in Figs. 1 to 1 and 6 The first fixed mold 52 (an example of the second mold) and the second fixed mold 53 (an example of the third fixed mold). Fig. 11 to Fig. 16 show a state in which the first resin and the second resin are not injected. In the example of the second embodiment, the decorative film 30 is not used only for the base sheet 2' in which the metal-based member 1 is embedded. Although not shown, the movable molds 5 1 A, 51 B are supported by the rotary table 15 in the same manner as in the above embodiment, and the first fixed mold 52 and the second fixed mold 53 are supported by the fixed stage 14. When the first fixed mold 52 and the movable mold 51A holding the base sheet 2 are closed, the first cavity 2 1 is formed between the base sheet 2 and the movable mold 5 1 A. Fig. 12 and Fig. 13 show a state in which the first resin is injected into the first cavity 21 to obtain the primary molded product F1. On the other hand, when the movable mold 51B holding the primary molded product F1 injected/molded by the previous step is clamped with respect to the second fixed mold 5 3, the base sheet 2 and the second fixed mold of the primary molded product F1 are clamped. A second cavity 22 is formed between 53. Fig. 15 and Fig. 16 show that the second resin 22 is injected into the second cavity 22 to obtain the secondary molded article F2. As shown in Fig. 16, between the movable mold 51 and the second fixed mold 5, an auxiliary cavity 71' for accommodating the protruding piece 2a of the base sheet 2 is formed for injecting the second gate of the second resin. 66 is a position where the second resin must pass through the auxiliary cavity 71 to be injected into the second cavity 22. As shown in Fig. 11, the protruding piece 2a' of the base sheet 2 protrudes from the substantially long side of one side of the base sheet 2 to have a rectangular shape. As shown in the XII-XII section (Fig. 12) of Fig. 11, a section is formed along a long side of the convex portion 5 1 b between the parting surface 51 a of the movable mold 51A and the convex portion 5 1 b. V-shaped groove 63. On the other hand, between the parting surface of the first fixed mold 52 and the concave portion 52b, a ridge 62 having a V-shaped cross section into which the groove 63 can be fitted is formed. Therefore, if the movable mold 51A and the first fixed mold 52 are clamped, one side surface 6 2 a of the protrusion 62 will contact one side surface 6 3 a of the groove 6 3 while being passed through the other side 62b of the protrusion 6 2 ( An example of the pressing portion) and the other side surface 63b of the groove 63 (an example of the pressing portion) grip the protruding piece 2a of the base sheet 2. As shown in the χιιι-χπι cross section (Fig. I3) of the η, 12, and 11th drawings, when the movable mold 51A and the first fixed mold 52 are clamped, the movable mold 51 A and the first fixed mold 52 are A first communication passage 61 that allows the first gate 57 and the first cavity 21 to communicate with each other is formed. The first resin injected from the U-port 57 is injected into the first cavity 21 through the first communication channel 61. The first communication passage 61 includes a first communication portion 58 formed between the parting surface 51a of the first movable mold 51A and the parting surface 52a of the first fixed mold 52, and is formed in the first communication portion 61. A linear second communication portion 59 between one side surface 62a of the ridge 62 and one side surface 63a of the groove 63, and another side surface 62b formed on the other side 62b of the ridge 62 and the groove 63 -23-201116396 The third communication unit 60 is in between. The third communication portion 60 is widened from the second communication portion 59 toward the primary molded product F1. The second communication portion 59 is connected to the first communication portion 58 in a meandering manner, and the third communication portion 60 is connected to the second communication portion 59 in a meandering manner. On the other hand, as shown in the XV-XV section (Fig. 15) of Fig. 14, a V-shape in which the groove 63 can be fitted is formed between the parting surface 53a of the second fixed mold 53 and the recess 53b. The ridge 72 » Therefore, if the movable mold 51B and the second fixed mold 53 are clamped, one side surface 72a of the ridge 72 contacts one side surface 63a of the groove 63 while being pressed by the other side 72b of the ridge 72 An example of the portion) and the other side surface 63b of the groove 63 (an example of the pressing portion) grip the protruding piece 2a of the base sheet 2. As shown in the XVI-XVI cross section (Fig. 16) of Fig. 14, Fig. 15, and Fig. 14, when the movable mold 51B and the second fixed mold 53 are clamped, the movable mold 51B and the second fixed mold 53 are closed. The second communication channel 70 that connects the second gate 66 and the second cavity 22 to each other is formed, and the second resin that is emitted from the second gate 66 is injected through the second communication channel 70. Cavity 22. The second communication passage 70 includes a linear first communication portion 67 formed between the parting surface 51a of the second movable mold 51B and the parting surface 53a of the second fixed mold 53, and is formed on the protrusion 72. A linear second communication portion 68 between one side surface 72a and one side surface 63a of the groove 63, and a third communication portion 69 formed between the other side surface 72b of the protrusion 72 and the other side surface 63b of the groove 63 . The third communication portion 69 is widened from the second communication portion 68 toward the primary molded product F1. The second communication portion 68 is connected to the first communication portion 67 in a bent shape, and the third communication portion 69 is connected to the second communication portion 68 in a bent shape. Between the other side surface 72b of the ridge 72 and the other side surface 63b of the groove 643, an auxiliary cavity 71 for accommodating a part of the protruding piece 2a of the base sheet 2 is formed. Here, the third communication portion 69 that exposes a part of the protruding piece 2a of the base sheet 2 constitutes the auxiliary cavity 71. As a result of forming the communication channel 70 as described above, the space in which the second resin passes through the protruding piece 2a in the vicinity of the auxiliary cavity 71 and the second fixing die 53 can always contact the base sheet 2 when the second resin is injected. Therefore, even if the high temperature second resin contacts the base sheet 2 and transfers the heat of the second resin to the base sheet 2, the heat received by the base sheet 2 can be transmitted to the movable mold 51B (51A) through the large-area protruding sheet 2a. The heat is dissipated, so that the base sheet 2 does not become excessively high in temperature, and the base sheet 2 is prevented from being melted. As a result, the position at which the position of the metal-based member 1 embedded in the base sheet 2 is shifted can be suppressed. Further, at the time of mold clamping, as shown in Figs. 11 and 12, the both side portions 2c, 2d of the protruding piece 2a which are not overlapped with the third communication portion 60 are held by the movable mold 5 1 A and the first one. Between the fixed molds 52. Therefore, when the first resin is injected into the first cavity 21 from the first gate 57 and the first resin layer 25 is formed on the lower surface of the base wafer 2, the first resin does not enter the gap between the other side surface 62b. . Further, as for the second fixed mold 5 3 and the movable mold 5 1 B, as shown in Figs. 14 and 15 , the both side portions 2f and 2g of the protruding piece 2a that are not overlapped with the third communication portion 69 are held. It is fixed between the movable mold (51B) 51A and the second fixed mold 53. Therefore, when the second resin injected from the second gate 66 is injected into the second cavity 22 and the second resin layer 26 is formed on the side where the metal base member 1 of the base sheet 2 is embedded, the second resin does not enter and the other resin The side between side -25 - 201116396 face 63b. Then, the movable mold 51B and the second fixed mold 53 are opened, and the secondary molded product F2 is removed from the movable mold 5 1 B. In addition, as the finishing, the projecting portion 2a of the protruding outer portion of the secondary molded product F2, which is removed from the movable mold (5 1 B ) 5 1 A, and the protruding portions of the first resin layer 25 and the second resin layer 26 are cut. Broken (refer to Figure 17). In this case, since the protruding portion of the protruding piece 2a, the first resin layer 25, and the second resin layer 26 from the one side of the secondary molded article F2 is formed to protrude, it is only necessary to perform the cutting once, and it is possible to obtain Reduce steps and productivity. In addition, since the protruding piece 2a' is held by the movable mold 51A, the first fixed mold 52, the movable mold 51B, and the second fixed mold 53, the structure for holding the protruding piece 2a is not separately provided, and the structure can be constructed. simplify. Further, a plurality of gates may be provided to take out a plurality of molded articles. [Third Embodiment] The third embodiment shown in the following Figs. 20 to 27 is mainly explained with respect to the structure different from the structure of the first embodiment, and the description of the same configuration will be omitted. As shown in Fig. 20, the molding die used in the third embodiment includes a first fixing die 182 (an example of a second die) supported by the fixing platform 14, and a second fixing die 183 (an example of a third die) And the movable molds 1 8 1 A and 1 8 1 B supported by the rotating platform 15 (an example of the first mold). The rotary platform 15 is rotatable relative to the fixed platform 14 and is capable of retreating. Here, the fixed molds 182 and 183 are concave mother molds, and the pair of movable molds 181A and 181B are convex male molds. As shown in Fig. 20, in the concave portion of the first -26-201116396 fixed mold 182, the base sheet 2 to which the metal key member 1 is attached is locked, and the decorative film 30 is placed in the concave portion of the second fixed mold 184, and The fixing is performed by the fastening tool 33. On the other hand, the primary molded product F 1 obtained in the previous step is locked to the convex portion of the second movable mold 181B. This primary molded product F 1 has the same shape as the primary molded product F 1 shown in Fig. 22. Next, as shown in Fig. 21, when the rotary table 15 is pressed toward the fixed stage 14, the first fixed mold 182 and the movable mold 1 81 A are clamped, and the second fixed mold 1 83 and the movable mold 181B are closed. The first fixed mold 182 and the movable mold 1 81 A are clamped, and as shown in the upper portion of Fig. 21, a base sheet 2 and a first movable mold 1 8 1 A that are locked to the first fixed mold 182 are formed. The first cavity 2 1 for accommodating the first resin. When the first resin is injected into the first cavity 21, the first resin is welded to the inner surface of the base sheet 2, and the base sheet 2 (sheet layer 3) in which the metal-based member 1 is embedded and the first resin layer 25 are obtained. The primary molded product F 1 is constituted. The second figure shows the state after the first resin is injected. On the other hand, as shown in the lower part of Fig. 21, when the second fixed mold 183 and the movable mold 181B are clamped, the primary molded product F 1 that is locked to the movable mold 181B and the second fixed mold 1 8 3 are locked. Between the decorative films 30, a second cavity 22 is formed, and a second resin is injected therein. Actually, the decorative film 30 is adsorbed on the inner surface of the concave portion of the second fixed mold 183 before the second resin is injected. In order to achieve this adsorption, a plurality of fine suction holes (not shown) are provided in the concave portion of the second fixed mold 1 83, and a negative pressure is generated in the inner surface of the concave portion of the second fixed mold 183 to transmit the suction hole. Pump (not shown). This suction mechanism is also provided on the first fixed mold 182. -27- 201116396 As shown in the enlarged view of the main part of Fig. 21 (Fig. 24 and Fig. 25), two protruding pieces are formed on the base sheet 2. One of them is the first projecting piece 2A that linearly extends from a part of the four edge portions of the base sheet 2. The other is a second projecting piece 2B which is bent outward from a part of the opposite side. The first protruding piece 2A and the second protruding piece 2B are pressed against the inner surface of the first fixed mold 182 between the forming steps shown in Fig. 20 and Fig. 21, and the final secondary molded article F2 The protruding pieces 2A, 2B are cut off. As shown in Fig. 25, when the second fixed mold 183 and the movable mold 181B are clamped, the first projecting piece 2A is housed in the first auxiliary cavity 136a formed in the movable mold 181B. Further, the second gate 139 for injecting the second resin is provided at a position where the second resin is required to pass through the region in which the auxiliary cavity 136a of the first projecting piece 2A is provided to be injected into the second cavity 22. Further, as shown in Fig. 24, when the first fixed mold 182 and the movable mold 181A are clamped, the second projecting piece 2B is housed in a part of the second auxiliary cavity 132a formed in the movable mold 181A. When the curing of the first resin and the second resin injected in the step of Fig. 2 is completed, as shown in Fig. 22, the rotary table 15 is separated from the fixed stage 14, and the movable molds 181A and 181B are respectively removed from the first fixed mold. 182. The second fixed mold 183 performs mold opening. In this state, the primary molded product F1 molded by the convex portion of the first movable mold 181A is supported, and the formed secondary molded product F 2 is supported by the convex portion of the second movable mold 181B. The secondary molded product F 2 is taken out from the second fixed mold 183, and as shown in Fig. 23, the rotary table 15 is rotated by 180 degrees, and the step from Fig. 20 can be repeated. The removal process of the protruding pieces 2A, 2B and the like is performed on the taken-out secondary molded product F2'. -28- 201116396 Here, the steps of Fig. 20 and Fig. 2 are re-described in detail. First, as shown in Figs. 21 and 24, when the first fixed mold 182 and the movable mold 181A are clamped, the first gate 138 and the first cavity 21 are formed between the two molds 182 and 181A. Connected communication flow path 140. The communication flow path 144 includes a linear first communication portion 1400A that directly communicates with the outlet of the first gate 138, and a linear second communication portion that directly communicates with the outlet of the first cavity 21. 140B. The second communication portion 140B and the first communication portion 140A extend substantially parallel to each other and are connected to each other in a crank shape. On the inner surface of the first fixed mold 810 corresponding to the joint boundary, a retracted portion 1 8 2X which is recessed stepwise toward the fixed stage 14 side is formed along the entering direction of the first resin. Further, the front end of the second projecting piece 2B of the base sheet 2 is opposed to each other so as to be pressed by the retracted portion 182X, whereby the first resin flow can be prevented from causing floating and "curling" of the base film 2, and the like. The depth of the retracted portion 182X exceeds the thickness of the base sheet 2. Next, as shown in Figs. 21 and 25, when the second fixed mold 183 and the movable mold 18 1 B are clamped, the second gate 1 is formed between the two molds 1 8 3 and 1 8 1 B. A communication path 1 42 in which the 3 9 and the second cavity 22 communicate with each other. The communication passage 142 is formed by the second auxiliary cavity 136a, and includes a linear first communication portion I42A that reaches the vicinity of the fastening tool 33 from the second gate 139, and along the fastening tool 3 The second communication portion 142B that enters the lower side surface 3 3b of the third portion and enters the rotation platform 15 , and the third communication portion 142C that extends upward along the upper surface 33 c of the fastening tool 33 , along the fastening device The upper side surface 33d of the 33 is adjacent to the fourth communication portion 142D of the second fixed mold 183. The fourth communication portion 142D belonging to the final portion of the communication flow path 142 extends in the lateral direction of the second fixed mold 183 toward the second fixed mold 183, and is on the boundary surface between the second fixed mold 183 and the movable mold 181B. The end portion of the fourth communicating portion 142D (an example of a flow path portion facing the protruding piece) and the entrance portion of the second cavity 22 are substantially linearly connected to each other without an angle. Specifically, the base end portion of the upper side surface 33d in the drawing of the fastening tool 33 shown in Fig. 25 coincides with the end surface position of the final secondary molded article F2 at the point S. In the fourth communication portion 142D, a retracted portion 142X (an example of a stepped recess) which is recessed in a stepwise manner toward the center line of the movable mold 181B is formed along the entering direction of the second resin. Further, the front end of the first projecting piece 2A of the base sheet 2 is opposed to be pressed by the retracted portion 142X, whereby the second resin flow can be prevented, and the floating and "curling" of the base sheet 2 can be caused. Wait. The depth of the retraction portion 1 42 X exceeds the thickness of the base sheet 2 . As a result of forming the communication channel 142 as described above, when the second resin is injected, the second resin can always contact the substrate sheet 2 in the second cavity 22 through the space surrounded by the first projecting piece 2A and the fastener 33. . Therefore, even if the second resin having a high temperature contacts the base sheet 2 and transfers the heat of the second resin to the base sheet 2, the heat received by the base sheet 2 can be transmitted through the gradually widening projection which widens in the direction in which the second resin enters. Since the sheet 2A is efficiently radiated to the movable mold 181B, the base sheet 2 in the second cavity 22 does not become excessively high in temperature, and the melting and metal tone of the main body portion of the base sheet 2 assembled to the final secondary molded article F2 are prevented. Deformation of the member 1 and the like. Further, since the first protruding piece 2A is formed into a gradually widened shape, even if the heat transferred from the second resin to the first protruding piece 2A of the base sheet 2 is first diffused in the width direction of the first protruding piece 2A, it is transferred to the first 1 The base sheet 2 other than the protruding sheet 2A can prevent the high temperature of the -30-201116396 portion of the base sheet 2 from becoming high. As a result, the phenomenon in which the position of the metal key member 1 embedded in the base sheet 2 is shifted can be suppressed. In addition, as described above, the entrance portions of the second cavity 22 of the terminal portion of the fourth communication portion 142D are substantially linearly connected to each other without an angle, and the second resin layer is injected from the second gate 139 in the molding step of the second resin layer. The second resin is injected along the extending direction of the first protruding piece 2 A in a state in which the fourth communication portion 1UD facing the first protruding piece 2A is connected along the second cavity 22 . In other words, the second resin at this time is not in contact with the front surface of the first protruding piece 2A of the base sheet 2 and the main portion of the final secondary molded article F2, but is smoothly along the main portion of the base sheet 2. It flows through and enters the second cavity 22. Therefore, compared with the structure in which the resin injected from the second gate 139 comes into contact with the base sheet 2 and enters the second cavity 22, the possibility of precipitation of the second resin in the vicinity of the base sheet 2 is reduced. 2 The influence of the heat of the resin is not easy with the base sheet 2. Further, as described above, the base end portion of the upper side surface 33d in the drawing of the fastening tool 33 shown in Fig. 25 coincides with the end surface position of the final secondary molded article F2. In other words, the decorative film 30 is pressed on the second fixed mold 183 by the fastening tool 33 in the position before the portion where the decorative film 30 is to be assembled on the main portion of the final secondary molded article F2. The decorative film 30 floats from the inside of the concave portion of the second fixed mold 183. [Fourth Embodiment] As shown in Fig. 26, the metal base member 1 attached to the base sheet 2 is formed such that a part of the peripheral surface portion 1 A is convex toward the surface side -31 - 201116396, and is formed. The closer to the peripheral side, the smaller the thickness of the member. Further, as shown in Fig. 27, in the secondary molding, the second resin is injected so as to flow from the peripheral portion side having a small thickness of the metal-based member 1 toward the metal-based member 1. Thus, the frictional force generated by the contact between the surface portion of the metal-based member 1 and the second resin can be reduced, and the position of the metal-based member 1 of the sheet layer 3 can be suppressed from shifting. Further, in the case where the side portion of the metal-based member 1 is vertically planar, the surface area of the side portion becomes large, and the three-dimensional feeling of the metal-based member 1 can be further increased when the resin molded article is observed from the outside. [Fifth Embodiment] As shown in Fig. 28, after the metal base member 1 is attached to one surface of the base sheet 2, the base sheet 2 is covered with another resin so as to cover the metal base member 1. In this manner, by providing the coating layer 4 on the surface of the metal-based member 1, as shown in Fig. 29, when the second resin is injected, the metal-based member 1 of the sheet layer 3 can be protected by the coating layer 4, and further The metal base member 1 of the sheet layer 3 is prevented from being displaced. Although various resins can be used for the coating layer 4, it is preferred to use the same resin as the second resin. In this manner, when the coating layer 4 and the second resin layer 26 formed of the second resin are formed into a body, and the resin molded article (metal-based decorative resin molded article) F2 is viewed from the outside, the coating layer 4 can be reduced to the metal-based member. The effect of the aesthetics of 1. [Other Embodiments] (1) The structure exemplified in each of the above embodiments is a movable mold for holding the first resin layer 25 and the base sheet 2 (an example of the first mold - 32-201116396), and is formed. The second resin is injected into the space surrounded by the protruding piece and the second fixed mold (an example of the third mold) which is combined with the movable mold (an example of the first mold). However, in place of this structure, a protruding piece that protrudes outside the secondary molded product F2 is formed in the first resin layer 25, and a movable mold (an example of the first mold) for holding the first resin layer 25 and the base sheet is allowed. The protruding piece of the first resin layer 2 5 is in contact with the second resin crucible (the space surrounded by the protruding piece and the second fixed mold (an example of the third mold) combined with the movable mold (an example of the first mold). 2) As shown in Fig. 30, the width of the second cavity 22 (corresponding to the thickness of the second resin layer 26 of the metal-based decorative resin molded article) may be larger than the thickness of the first resin layer 25. For example, when the thickness of the base sheet 2 is 75 to 200 μm as described above, and the thickness of the first resin layer 25 is 0.6 to 1.2 mm, the width of the second cavity 22 (corresponding to the thickness of the second resin layer 26) It is larger than the thickness of the first resin layer 25. As described above, when the second resin is embedded in the metal-based member 1 of the base sheet 2, the shear stress generated by the metal-based member 1 becomes small. As a result, the force acting in the flow direction of the second resin of the metal-based member 1 becomes small, and the metal-based member 1 is less likely to be displaced from the buried position of the base sheet 2. (3) In the structure described in the above embodiment, the decorative portion 30a is transferred onto the surface of the second resin layer 26 by using the decorative film 30 (transfer foil), but it may be replaced by a plain The base sheet or the insert sheet obtained by imparting a pattern or the like on the base sheet is directly integrated or formed into a structure in which the decorative film 30 and the embedded sheet are not used. Further, the decorative film 30 may be in the form of a sheet -33-201116396, and the embedded sheet may also be in the form of a film. (4) The structure 'fixing means exemplified in the first embodiment is the sliding block 17 that grips the edge portion 2b of the base sheet 2. However, the structure is not limited to such a structure. For example, the fixing means may be the attraction of the attraction edge portion 2b. means. (5) The multilayer molding machine exemplified in the above embodiment includes a rotary table 15 and a fixed platform 14. The rotating platform 15 has two movable molds (an example of a first mold) that can advance and retreat in a lateral direction and can rotate around a core in a lateral direction; the fixed platform 14 has a first fixed mold (second mold) An example) and a second fixed mold (an example of a third mold). However, it is not limited to such a multilayer molding machine. For example, in the primary molding, the first mold and the second mold are clamped, and the secondary molding is performed, and the sliding mold is provided in the second mold. An example of the mold is to retreat to form a second cavity between the first mold and the first mold, and to emit the second resin to the second cavity. Further, a multilayer molding machine including a first movable platform and a second movable platform; the first movable platform having a movable mold (an example of a first mold) and capable of advancing and retreating in a vertical direction; and the second movable platform; The first fixed mold (an example of a second mold) and the second fixed mold (an example of a third mold) are provided to be slidable in the lateral direction. Further, a multi-layer molding machine including a movable platform and a rotating platform; the movable platform has a movable mold (an example of a first mold) and can advance and retreat in a lateral direction; and the rotating platform is a first fixed mold (second An example of the mold and the second fixed mold (an example of the third mold) are mounted back to back and are rotatable about a straight axis. (6) As a modification of the second embodiment, for example, in the eighth diagram and the i9th diagram, 'the -34- is formed between the parting surface 51a of the movable mold 51 and the convex part 51b. 201116396 The inclined portion 7 3 on the movable mold 5 1 side; the first fixed mold 5 2 side facing the inclined portion 7 3 is formed between the split surface 5 2 a of the first fixed mold 5 2 and the concave portion 5 2 b The inclined portion 7 4 is formed between the parting surface 5 3 a of the second fixed mold 53 and the recess 5 3 b, and the inclined portion 7 5 on the second fixed mold 53 side facing the inclined portion 73 is formed; Between the mold 51 and the first fixed mold 52, a first communication passage 7 6 for injecting the first resin injected from the first gate 57 into the first cavity 2 1 is formed; in the movable mold 5 1 A second communication passage 7 7 for injecting the second resin injected from the second gate 6 6 into the second cavity 2 2 is formed between the second fixed mold 53 and the second fixed mold 53.
